Pkg xen devel - Jul 2007 - xen kernel headers, new kernel modules with a-i

Hello Pkg-xen-devel list,

I am running lenny with xen-linux-system-2.6.18-4-xen-686 (xen 3.0.3)
installed. I'd like to put this server in the cupboard and access it
via wifi.

To build the wifi kernel module, it should hopefully go like this :

apt-get install madwifi-source madwifi-tools
m-a a-i madwifi
modprobe ath_pci ...

Except that I do not have the sources nor the headers of my kernel.

"apt-get source xen-linux-system-$(uname -r)" copied
linux-2.6-2.6.21{,6.diff.gz,6.dsc,orig.tar.gz} in my home dir, but
"m-a a-i madwifi -k linux-2.6-2.6.21" would not work any better...

I read (ok, grepped) the last year of the mailing list archive without
much results.

How can one do to install the madwifi kernel modules on a debian xen kernel?

Thank you

I have troubles to follow the last paragraph - you should not need to do
any apt-get source and whatever when using m-i, or did I get something
wrong?

Still, _normally_ it should work with just m-a a-i madwifi, right.

But you run a kernel that's hopelessly outdeated in lenny, and
currently, as there exist no Kernel patches for Kernels > 2.6.20, there
is in fact no Xen kernel in Debian lenny and unstable at the moment. So,
you are out of luck.

Maybe wait until the Xen developers have their (hopefully sometimes
complete, currently there is only domU support, and many important
features missing) stuff in upstream finally, and then use this kernel
with the "normal", included wifi drivers?

But m-a takes care of that himself, no need tfor you to call apt-get
spurce, AFAIK.

Yes, maybe - I don't know why that happened. Maybe also because there
just isn't any 2.6.18 kernel, neither in lenny, nor in unstable, nor in
sarge:

Yes, because you use sarge - you want Etch!

Your messages come through to the list (and please keep including the
list in your mails).

My sources.list were pointing to lenny while I had an etch installed.
Once fixed:
 - m-a takes care of the kernel headers transparently,
 - madwifi compiles and loads fine,
 - wpasupplicant is a breeze to configure thans to the debian wiki.

Thank you, I am a happy camper.
